PNEUMATlC-DESPATCH REC EPTACLE.

SPECIFICATION formingpart of Letters Patent N 0. 723,457, dated March 24, 1903. Application filed January 6. I902. Renewed January 22, 1903. Serial No. 140,178. (No model.)

To all whom it may concern.-

Be it known that I, EMANUEL C. GIPE, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Pneumatic-Despat-ch Receptacles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in which corresponding letters of reference in the different figures indicate like parts.

The object of my invention is to provide a pneumatic-despatch carrier or receptacle for carrying cash and for other analogous uses common to pneumatic-tube systems, which carrier shall be so constructed as to permit the air to surround the receptacle, so as to maintain it in .a central position within the despatch-tube, thereby reducing the friction to a minimum. I accomplish said object in the manner hereinafter more particularly do scribed, and specifically claims. V

In the drawings, Figure l is a perspective view of a pneumatic carrier embodying the features of my invention. Fig. 2 is a face view of one of the ends of said carrier. Fig. 3 is a sectional view of one of said carrier ends and a portion of the receptacle,said view being taken upon the line 3 3, Fig. 2, viewed in the direction of the arrow there shown.

pointed out in the Fig. 4 is a like view taken upon the line 4 4,

Fig. 2, viewed in the direction of the arrow there shown. Fig. 5 is an end view of the carrier represented in Fig. 1, showing the relative position of the bearing-surfaces upon the respective ends which bear against the pneumatic tube to receive said carrier, said tube being indicated in dotted lines. Figs. 6, 7, and 8 are diagrammatic views showing various rnodifications in the construction of the ends of saidcarrier. Fig. 9 is an end view of a modified form of carrier, showing the relative positions of. the bearing projections at the respective ends. Fig. 10 is a face view of one end of a still further modification; and Fig. 11 isa sectional view taken upon the line 11 11, Fig. 10.

In Fig. 1 of the drawings is shown a cylindrical receptacle of a well-known construction which consists of two hollow cylindrical shells a and b, the latter inclosed within the and the'oonduit or tube.

former, each being provided with the usual opening, so arranged that when the cylinders are turned in agiven position the openings will coincide, so as to enable money or other articles to be placed within or removed therefrom, and when rotated in an opposite position the receptaclemay be closed. A stop c up'on the inner cylinder serves to limit its rotation and to secure it in place.

I do not confine myself to any specific form of cylindrical receptacle, for the reason that my invention relates only to the end pieces therefor, which are of such a construction that they may be readily adapted or attached to any one of various forms of receptacle.

Rigidlysecured to each end of the carrying-receptacle is a knob or head 61, preferably made of wood, compressed fiber, felt, or other suitable material, the attachment being effected by means of screws e, Figs. 3 and 4, passing through the end of the shell into said knob, or in any other approved way. Preferably stretched over each knob is a partial coveringf, of leather, cloth, or other suitable material, so formed and disposed thereon as to form a series of three or moreperipheral projections g of such a thickness as to fit within the pneumatic tube, as indicated in dotted lines in Fig. 5, thereby leaving a series of spaces It between said projections, in which the air isfree to circulate between the knob d The knobs are preferably so placed with reference to each other upon the respective ends of the .receptacle that the projections g upon one end will lie in radial planes midway between those upon the opposite ends, as shown at g and 9', respectively, in Fig. 5. Should a covering of leather, felt, or the like be employed to form the projections, the flaps or ends may be drawn over upon the inner face of the knob, as indicated in dotted lines in Fig. 2 and shown in Figs.'3 and 4, and secured by means of tacks 2".

While I prefer to make the coverfin. a single piece from leather or rawhide and shaped in the manner shown, it is obvious that the form may be varied indefinitely so long as projections are formed thereby upon the periphery of the knob.

In Figs. 6, 7, 8, 9, and 10, respectively, I have shown modified forms of knobs in which no covering is indicated. These are preferably made from a light, durable, and tough material, like compressed fiber, and the airspaces may be made by cutting notches therein, as shown 'atj, Fig. 6, by cutting away the periphery, as shown at k, Fig. 8, by molding knobs l thereon, as shown in Fig. 7, or by inserting plugs m, Figs. 9, 10, and 11, in suitable bores formed in the periphery and allowing the rounded ends thereof to project, as shown. In Fig. 9 three such knobs are represented at equal distances from each other, and the two knobs are so disposed with reference to each-other that the projections upon one will lie in radial planes between those upon the other. In Fig. 10 four such knobs are employed, which is the number I prefer to use.

My improved device is cheap and durable and may be readily replaced when Worn.
